In the clearest indication yet that she and Justin Theroux are considering starting a family, Jennifer, 44, praised her partner's love of children and his nurturing side.

Speaking to her 'We're The Millers' co-star Jason Sudeikis in Glamour magazine, she said: ''I know Justin, for instance, has extremely amazing paternal instincts. Because [growing up] he had to sort of become the parent. I think when you have to become the parent when you're a younger person, you learn those instincts.''

Jennifer - whose first marriage to Brad Pitt ended in 2005 - also opened up about her tumultuous thirties and admitted she wished she could go back in time and advise her younger self to seek therapy to deal with everything that was going on.

She said: ''Thirties. Go to therapy. Clean up all of the s**t. Clean up all of the toxins and the noise. Understand who you are. Educate yourself on the self.

''You can undo a lot of things. If you're not happy, you can become happy. Happiness is a choice. That's the thing I really feel. Like with friends who refuse to get happy, who refuse to rise above the discomfort of where they're at.

''You actually deserve to have a family. And once you meet yourself, and truly love yourself, then you attract that. And look -I mean, the two of us have found these two, beautiful, loving, open people.''
